-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I don't think that's a limitation of the VCSA devices themselves, but rather how they are used. These devices show the screen as it currently is at any given time, although documentation for them is rather sparse. But couldn't we, rather than querying the device, monitor it instead for incoming text? I'll do some digging and see what I can find out. It just seems that to have speakup in the kernel even after removing serial support would leave us with all of the problems with none of the advantages remaining.
